Amulets, early 20th Century London, GPS and history collide in a new app from the Wellcome Trust based on Edward Lovett’s 1922 book Magic in Modern London.

The book detailed Lovett’s expeditions among London’s population at a time when the protective power of amulets was at the forefront of the public imagination.

The iOS app, which takes its name from Lovett’s book, invites the user to rediscover 64 of his amulets, which are spread across London in historically relevant locations.

On the way the user will hear specially commissioned soundscapes, see selected historical images, hear readings of Lovett’s book and unlock sections of text to read.
